When I was building up my Fuji, I used parts from my track bike/commuter, including the cheap Shimano BB. It only took a trainer session and a track day before the plastic non drive cup cracked, causing all sorts of fun noises. Obviously I need a more sturdy BB setup.The crank sets I can get through my shop are the Omniums, FSA Carbon Track, and Sugino 75. The Omniums are well known to be the best bang for the buck, as they come with a BB. I'm not really considering the FSAs, as they are the most expensive choice, and don't come with a BB. The Suginos don't come with a BB, but I can order either the cartridge bearing BB or the loose bearing, which gives me the option of using a low viscosity lube for race day. The downsides with the Omniums are well known. They have a thick spider which means chainring changes can be difficult, and frame clearance can be an issue, though my Fuji Track Pro has dimpled stays which solves that problem. They also have a wide Q-factor, which I am also okay with. Finally, I've read that a few years ago, the stock BB has less than stellar bearings. I've also read that they've since improved, but either way, a decent external BB plus the cost of some Omniums is still less than a Sugino 75 loose bearing BB and crankset.
Ultimately, I'm more tempted by the Omniums due to their cost effectiveness, in spite of the flaws. I should imagine that the two are very nearly the same in regards to stiffness, though I would imagine the Omniums to be stiffer, because of its external BB, and thicker spider and crank arms. Am I missing something here? Most of the advice that I've read tends to point people away from the Omniums for the purposes of strict track racing, but as the Sugino setup is my only alternative, which is the better buy?
